3DVerkstan Faceshield Stacker (Customizable)

thingiverse

I created a customizable OpenSCAD script that lets you easily pick the face shield variant you need and build vertical stacks to mass-produce them. If you have OpenSCAD and want to run this locally, download `run locally.zip`. This will be much faster than rendering in Thingiverse Customizer. **4/27/20 Edit**: I updated all variants to the solid front version, which prints in stacks much better. Unless your printer has really good bridging, the old version wouldn't work. This version will generate stacks that can be printed on pretty much any printer. **4/28/20 Edit**: I added 3 common stacks for North America face shield: 100mm, 180mm, and 200mm max build heights ### Features - Number of parts in a stack - either specify a number yourself or let the script calculate the max number of face shields that will fit in your build volume. - Variant selection - easily choose between one of the four (North America, Europe, Sweden, and Prusa visor compatible) - Customizable layer height and number of layers of gap between each face shield frame - Automatic spacing generation between each frame ### Explanation Thingiverse Customizer doesn't support the `import` command, so I made a [file converter that turns STL files into SCAD modules](https://www.thingiverse.com/thing:4461877). This results in a massive OpenSCAD file, as they all have to be in one file for Customizer to work. Originally, I simply used the `import` command to reference each STL, which results in much faster rendering and stack STL generation. `run locally.zip` contains the original .scad file that uses the `import` command, along with each referenced STL. ### Print Settings Do not use supports! (unless you have PVA or another dissolvable filament.) With a 0.4mm nozzle, a 0.25mm layer height works great with a 2 layer gap on my printer. If you are printing with a larger layer height, I suggest decreasing the layer gap to 1 layer. In order for the layer gap to work correctly, every layer must be an integer multiple of the layer height. This means the first layer MUST BE 100% of the layer height, or 200%, 300%, etc.
